Safety Data Sheets (SDS)

Safety Data Sheets (SDS)

Maricopa County, as an employer, must have copies of Safety Data Sheets (SDS) in the workplace where hazardous chemicals are used under 29 CFR 1910.1200, Hazard Communication.

If the employee, or the employee's supervisor, does not understand what an SDS is, how to read an SDS, or where they are located, he/she should contact the Risk Management, Environmental Division at 602-506-7179 for assistance. Remember, SAFETY works both ways - employees and employers are responsible for the SAFE operations.

To learn more about the Hazard Communication Standard, you can go to OSHA's Hazard Communication page, or by entering "29 CFR 1910.1200 inches as directed on the National Archives and Records Administration, Code of Federal Regulations page.

Incompatible Material

The staff of the Risk Management, Environmental Division periodically inspect all County facilities and include a review of chemicals used and stored at these sites. Many chemicals used and stored together may be incompatible. The Navel Occupational Safety, Health, and Environmental Training Center has prepared an "Incompatible Materials Chart" (loads slowly) which identifies 22 material groups, lists the incompatible groups, and indicates the reaction(s) if mixed.
